Bao is a type of Chinese steamed bun that is soft and fluffy. It is typically made from a simple dough of flour, water, and yeast, which is then filled with various ingredients. Common fillings include pork, chicken, vegetables, or sweet red bean paste. Bao can be enjoyed as a snack or a meal and is popular in many regions of China and beyond. There are different styles of bao, such as baozi, which are filled buns, and mantou, which are plain steamed buns without filling. Bao is often served with dipping sauces and can be found in restaurants, street food stalls, and at home.
